New Enterprise Requirements 16

D OMAIN R EQUIREMENTS  The meeting initiator can cancel or reschedule a meeting.  All participants can fully, partially or not attend a meeting.  The meeting can be scheduled to be one-time or recurring.  Meeting locations should be convenient 17

I SSUES IN D OMAIN R EQUIREMENTS "All participants can fully, partially or not attend a meeting." Problem:(Type of Issue: ambiguity) The statement sounds suggestive and partial attendance is not clearly defined. Option 1:Define partial attendance as the 50% or more participants attend the meeting. Option 2:Define partial attendance as same participant can attend different meetings partially. Option 3:Define partial attendance as same participant can attend different meetings partially but in non-overlapping manner. Solution:Option 3 18

I SSUES IN D OMAIN R EQUIREMENTS " The meeting can be scheduled to be one-time or recurring..” Problem:(Type of Issue: ambiguity) Here the word “recurrence” does not explicitly say when the meeting can be recurrent. Also the statement sounds suggestive and a more defined approach needs to be taken. Option 1:The meeting is recurrent every day at the time specified. Option 2:The meeting is recurrent every week at the day and time specified. Option 3:The meeting is recurrent every month at the date and time specified. Option 4:The meeting is recurrent every year at the date and time specified. Option 5:The meeting coordinator decides when the meeting should reoccur.. Solution:Option 5 19

F UNCTIONAL R EQUIREMENTS  FR18 Some meetings are scheduled and organized at the same time where partial attendance can be allowed  FR19 Each of the different type of user should have different access privileges  FR20 A secure login username and password is required for each of the user to access the system  FR21 A participant should only be able to see the meeting information that he/she initiated or is part of  FR22 A participant should only be able to search the meeting information that he/she initiated or is part of 20

I SSUES IN F UNCTIONAL R EQUIREMENTS ISSUE STATEMENT: [FR18] “Some meetings are scheduled and organized at the same time where partial attendance can be allowed.” Problem:(Type of Issue: ambiguity) The statement sounds vague and partial attendance is not clearly defined. Also who schedules and organizes these meetings isnt defined clearly Option 1:Define partial attendance as continue with holding the meeting even if 50% or more participants attend the meeting. Option 2:Define partial attendance as same participant can choose to attend or not attend different meetings partially as per his/her will. Option 3:Define partial attendance as same participant can attend different meetings partially but in non-overlapping manner. Solution:Option 3 21

ISSUE STATEMENT: [FR19] “Each of the different type of user should have different access privileges.” Problem:(Type of Issue: ambiguity) The statement sounds vague and here “different” in terms of user types and access privileges arent listed which would make the requirement more clear. Also the statement sounds suggestive and a more defined approach needs to be taken. Option 1:Define access privilege as any meeting participant shall be able to invite and include another participant to the meeting. Option 2:Define access privilege as any meeting participant shall not be able to include another participant to the meeting. He/She can invite another person to the meeting only through the meeting coordinator. Solution:Option I SSUES IN F UNCTIONAL R EQUIREMENTS

N ON F UNCTIONAL R EQUIREMENTS  NFR18 Information about meetings should be secure. 23

I SSUES IN N ON F UNCTIONAL R EQUIREMENTS ISSUE STATEMENT: [NFR18] “Information about meetings should be secure.” Problem:(Type of Issue: incompleteness) The requirement is incomplete as it does not specify what exactly expected by “secure” system and what information needs to be secure. i.e. the information about the participants or the meeting details. Option 1:Define security as the access privileges for each type of user. Users shall be able to log into the system via a login screen with a user name and password. A participant should only be able to see and search the meeting information that he/she initiated or is part of. Option 2:All participants will have same privileges. Option 3:Meeting details will be kept secret. Solution:Option 1 24
